NW technology: LAN, bonding, VLAN, NW protocol(TCP/ , UDP), load balancing algorithm etc
Design of HYDRA internal NW according to new HW (server, NIC, switch)
Solution for driver problem by having NW driver knowledge
Linux driver source code analysis/ modification maintenance in order to adjust HYDRA spec. Driver implementation to Linux
Vendor negotiation skill with Chelsio/Broadcom about driver
Skill against NW performance trouble (OS/ driver/ external NW/ Perf. Analysis/ packet dump)
Skill to analyze the intra-system communication. Holistic understanding on the HYDRA system structure and behavior is also required.
To keep the system communication volume controlled even in case of a failure,
we have a monitoring feature.
For carrying out HW maintenance activities (replacement of switch/ NIC etc) without stopping the system, software development and creation of maintenance procedure is required.
